iPhone has about:config?
Still worrying if they do end up baking something into the browser and hiding the Off switch behind an obscure setting
I don’t use iOS, so I don’t know for sure, but I assume yes. The Fennec build does on Android. I’m currently using the official Mozilla Firefox build on Android because of the Fennec guys breaking their build, and it looks like they only have it enabled by default in the nightly and dev builds…but it’s present in the regular builds as well, just off by default, and you can flip it on.
You need to go to
chrome://geckoview/content/config.xhtml
, and it’ll have said advanced settings. By default, Firefox-on-Android will eat thechrome://
bit if you paste it into the field, so you want to be sure to have that there.There’s also a setting there,
general.aboutConfig.enable
. If you set that to True, it’ll makeabout:config
also go to the advanced settings page.
